[Miami M3]

I haven't seen them in person, but judging by the pictures it doesn't look like they sit much lower than the stock bumper would. Can anyone confirm how much lower (if at all) the splitters make the bottom of the bumper sit? I'm asking because I have some pretty steep garage entrances that I use daily and I don't want to order them and watch them pop off as soon as I go up or down the incline. Thanks.
